So I just purchased a Sig Scorpion government model 1911 with the night sights and threaded barrel. I am having a hard time finding a decent holster for it and I do not have any desire to have an in the waist band holster. Some posts online state the Blackhawk! Serpa holsters (level two's and three's) will work fine with the Sig's bulkier or squarer slide but I am a little leary of ordering a holster and then not having it work. Can anyone tell me if the Blackhawk! holsters will work with the Sig 1911?
